Assessing The Impact Of Unbalanced Resources And Communications In Edge Computing

Edge computing relies on devices at the edge of the network to best meet the application's needs, such as low communication latency and data caching. However, unbalanced networks and resource heterogeneity are challenging factors when optimizing data transfers and applications' performances in the edge. In this paper, we explore these two concerns through a comprehensive set of benchmarks and illustrate their importance with the help of two elements that should be part of any edge computing toolkit: data locality and context awareness. Thanks to the benchmarks, we highlight some pitfalls and opportunities that may be met when trying to deploy applications on the edge. (C) 2020 Elsevier B.V. All rights reserved.
